Large-scale grid-connected batteries unveiled in Vic

battery storage trial

The first of two large-scale batteries that will support Victoria’s energy grid has been unveiled in Ballarat.

Minister for Energy Lily D’Ambrosio today opened the Ballarat Energy Storage System (BESS), located at the Ballarat Terminal Station in Warrenheip.

The BESS is a state-of-the-art lithium ion large-scale battery that will deliver a 30-megawatt/30-megawatt hour supply which is capable of powering more than 20,000 homes for an hour of critical peak demand before being recharged.

The BESS will be able to respond to changing grid needs within milliseconds and will operate 24 hours a day, seven days a week to support critical peak demand.

Australian Renewable Energy Agency CEO Darren Miller said the batteries will help improve grid stability in Western Victoria.

“As we have seen with the success of large-scale batteries in South Australia, grid-scale batteries have an important role to play in providing short-term energy storage and providing rapid response injections of power to help stabilise the grid,” he said.

“This battery will help to ease constraints on transmission lines in Western Victoria that currently curtail the output of wind and solar, while also helping to bring in more renewables to the grid.”

It’s one of two large-scale batteries that are part of the Labor Government’s Energy Storage Initiative, which is supporting energy storage technologies, driving the development of clean technologies and boosting local economies.

The second large-scale battery is the Tesla 25 megawatt/50 mega-watt hour battery which is integrated with the Gannawarra Solar Farm, south-west of Kerang.

This battery will store renewable energy on site. Delivered by Edify Energy, it is also expected to provide grid support by summer 2018.

In March, on behalf of the Australian Government, ARENA committed $25 million to the two grid-connected, utility-scale batteries, matching the $25 million committed by the Victorian Government as part of its $50 million energy storage initiative.

A consortium led by Downer Spotless completed the battery, supplied by technology provider Fluence, in October.

BESS is owned by AusNet Services and operated by EnergyAustralia.
